Primary carcinoma of ureters.

Thirty-two patients with primary carcinoma of the ureter were treated at our institution from 1961 to 1968 using various modes of therapy. Sixteen of these patients underwent segmental resections, with a five-year survival of 71.4 per cent and a ureteral recurrence rate of 6 per cent. Twelve other patients received a complete nephroureterectomy, with a subsequent five-year survival of 50 per cent. We believe that segmental resection is indicated for all low-grade and low-stage primary ureteral tumors regardless of their location and with a small change for recurrence.
